Abstract
The visual world contains more information than can be understood in a single glance. As a result, observers build representations of scenes over time, a constraint on scene processing that requires the interaction of memory and perception. Using a temporal integration paradigm, subjects had to integrate information from temporally separated visual presentations into a single representation in order to accomplish a behavioral task. The primary focus of the experiments presented here was to explore the role of attention during this image percept integration process. Results indicated that observers maintain a memory representation that is veridical, but flexible enough to be generated and maintained independently of eye movements, to be retained across saccades to allow information displayed in unique spatial locations to be integrated, and to be manipulated to combine stimuli that vary in their spatial properties. These results suggest that as time elapses during scene processing, visual memory and perception can interact such that information from both sources can be integrated and that given time to accrue knowledge of the visual world in memory, more complete visual representations of the world can be constructed.
